There’s a 6-mpg spread between the thriftiest and thirstiest 2015 minivans. Here’s how these family-friendly people movers stack up when it comes to fuel economy.

Listed below is every 2015 model-year minivan ranked by fuel economy, as per the EPA. Included is the EPA’s estimated annual fuel cost for each model (which is calculated assuming 15,000 miles of driving and a fuel price of $2.80 per gallon).

You’ll likely note that the list below is more or less split between “traditional” minivans such as the Honda Odyssey and Toyota Sienna, and a new group of more-compact vans including the Ford Transit Connect and Ram ProMaster City.

Obviously, your real-world mileage will vary. However, the EPA ratings are an excellent resource for comparing the relative efficiency of vehicles in any class. What kind of mileage our you seeing with your minivan? Let us know.
